EatingBiting Double-Compartment Betta Fish Tank, 1.8 L with Removable Divider

EatingBiting’s double-compartment fighting fish isolation box is a compact plastic aquarium for ornamental fish, measuring 19 × 9 × 14 cm and holding about 1.8 litres.

• Removable, double-sided divider — houses up to two Bettas separately or creates one open compartment.
• Built-in divider slits — allow water to flow between the two sides.
• Opaque and see-through divider options — let you manage whether the fish can see each other.
• Filter grid, waste-absorbing Pro-V Crystals and two plastic plants — provide the included setup components.
• Bottom water-release cap — gives you a way to drain water during changes.

This small isolation box is made for keeping ornamental fish in a compact aquarium, with a divided layout designed for Betta housing. Its plastic construction is intended to be durable and sturdy. The product is also suitable for shrimp and clownfish, giving it use beyond Betta setups. Its compact size and divided arrangement make it suited to a dedicated small-scale fish-housing setup rather than a large aquarium.

Can it house two Bettas in one aquarium?

Yes, the removable divider separates the tank into two compartments so you can house up to two Bettas in the same aquarium without placing them together in one compartment. Bettas are naturally combative, so the divider keeps them apart. It has built-in slits to allow water flow between the compartments, and it can be taken out completely when you want one larger space for a single Betta.

• The divider is double-sided and removable.
• Keep both sides of the wall down to limit the fish’s view of one another.
• Lift and remove the colored side to allow visual display and flaring.

What comes with the fish box?

The kit includes a filter grid, waste-absorbing Pro-V Crystals and two plastic plants. These components are placed in the tank as part of the setup, alongside dechlorinated water. The box weighs 292 g, and its capacity is about 1.8 litres, giving you a compact enclosure with the listed setup pieces.

• One filter grid.
• Waste-absorbing Pro-V Crystals.
• Two plastic plants.

How do you set it up and change the water?

Wash all components with warm water only, then spot-dry them with a clean towel or rag. Place the filter grid, crystals and plants in the tank, and fill it with dechlorinated water. About once a week, or as needed, open the bottom water-release cap to drain about 20% of the water, then refill with dechlorinated water.

• Use warm water only to wash the components.
• Drain about 20% of the water for a change.
• Refill with dechlorinated water.

Which ornamental fish is this box suited to?

It is made for ornamental fish and is suitable for Bettas, shrimp and clownfish. For Betta use, the divider supports separate housing in one tank, while removing it gives a single Betta more room within the box. The transparent plastic construction lets you view the fish, and the divider’s opaque and see-through sides give you options for managing visibility between compartments.

• Overall size: 19 × 9 × 14 cm.
• Plastic construction.
• Designed for ornamental fish housing.

This box is a fit for fish keepers who want a compact ornamental-fish enclosure with the option to separate two Bettas or use one open compartment. It is designed for small-scale housing, with a 1.8-litre capacity and a removable divider.
